Metal-plastic pipes have characteristics that are not inferior to either plastic or metal pipes; Next, it will be described how the connection of metal-plastic pipes is made.
First of all, you need to figure out what you need to work. Naturally, the pipes themselves are needed. They are sold in rolls and look like white hoses used for watering. Diameters can be as follows: 16, 20, 26, 32 and 40 millimeters. You must decide which diameter suits you best. The connection of metal-plastic pipes for a private apartment water supply is usually carried out using pipes with a diameter of 16 or 20 millimeters. The sale of this type of material is carried out by footage, so it is worthwhile to determine in advance the required length of the water supply. You will be rewound in one single piece exactly as many meters asrequired. The next thing you'll need is fittings, which includes couplings, tees, and elbows. Fittings are selected depending on the diameter of the pipes. It is worth noting that if you need to connect metal-plastic pipes with metal ones, then you must purchase couplings and elbows. You only need to check the diameters of both pipes in the store so that the seller issues adapters of the required sizes.
If you are interested in connecting metal-plastic pipes, then you will need a gauge designed to slightly increase the pipe in diameter, so that the fitting cone will fit freely in the pipe, while the gaskets will not be subject to strong pressure. If you do not calibrate, then there is a high probability of rupture of the gasket. Another important tool that you will need for your work is a hacksaw (or special scissors). You should also choose different sizes of keys to suit your needs.
To perform the connection of metal-plastic pipes, it is necessary to perform a number of simple manipulations. To begin with, it is worth putting a nut with a crimp washer on the end of the metal-plastic pipe. After that, with the help of a caliber, it is required to make the diameter of the pipe a little larger, for which it must be screwed into the lumen of the pipe with uniform movements in a circle. A fitting cone can be inserted into a calibrated pipe. Next, you need to tighten the nut, which will allow the washer to slowly compress the pipe.
Fittings and pipes can be mounted using threaded connections or press systems. The first case involves the use of a sharp cutter, calibrator, and adjustable wrench. Press connection of metal-plastic pipes involves the use of special equipment. This process is much simpler, but the connection is less reliable. For work, you will need to use press tongs. The press fittings have a special plastic insert with a spacer ring designed to control the relative position of the fitting and the pipe, as well as provide insulation to the inner layer of the pipe.
According to one of these principles, you can connect the water supply by cutting the pipes to the required sizes, as well as selecting fittings.
